Technical Field

[0003] After searching, the Chinese invention patent with publication number "CN118068144A" discloses "an insulation testing device". The application includes a power supply, an insulation test module and a channel switching combination circuit connected in sequence. Among them, the channel switching combination circuit is used to connect multiple cables to be tested to the insulation test module in sequence for insulation testing, realizing low-cost, large-capacity, serialized online insulation performance testing, reducing manual participation, improving operational safety and detection efficiency, meeting the requirements of the railway signal centralized monitoring system, and ensuring the reliable and safe operation of the railway signal system. In addition, through the combination of fixed relay states, a certain cable can also be tested separately.

[0004] The Chinese invention patent with publication number "CN118534192A" discloses "an insulation resistance testing device". This application uses a voltage generation module to output negative polarity DC voltages of different levels, and uses a sampling module to continuously collect the current and voltage of the device under test, and generates a test report based on the current and voltage of the device under test, so that the test device can automatically test the insulation resistance of the device under test, thereby effectively improving the test efficiency of the insulation resistance and reducing the test cost of the insulation resistance. At the same time, due to the continuous collection of the current and voltage of the device under test and the generation of a test report based on the continuously collected current and voltage, the test data of the insulation resistance of the device under test by the test device is more comprehensive, thereby effectively improving the test accuracy of the insulation resistance.

DETAILED DESCRIPTION

[0051] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] Before understanding the technical solution proposed in this application, it should be clear that the insulation test of high-voltage cable joints is generally achieved by using an intelligent insulation tester, where the intelligent insulation tester is a common device in the field of insulation testing at this stage. When the intelligent insulation tester performs insulation testing on the high-voltage cable joint, it generally applies voltage and measures the current passing through the device or line to calculate the insulation resistance value. The insulation resistance value reflects the insulation performance of the device or line and is an important indicator for evaluating its electrical safety. It should be added that the intelligent insulation tester requires external test wires, clamps and grounding devices (grounding clamps) during actual measurement. The test wires are used to connect the intelligent insulation tester and the high-voltage cable joint under test, the clamps are used to fix the connection between the test wires and the cable joint, and the grounding device (grounding clamp) is connected to the ground to ensure safety during the test process. The test wires, clamps and grounding devices (grounding clamps) are respectively installed at terminal 406.

[0053] However, after measuring the insulation of the high-voltage cable joint, the intelligent insulation tester needs to be discharged to avoid the influence of charge accumulation on subsequent tests.

[0058] It should also be noted that, in the present invention, the sealing assembly 3 is used to seal the insulating test circuit board 204.

[0066] In addition, reference Figures 1-9 It can be seen that in the present invention, the energy supply component 1 is installed at one end outside the intelligent insulation tester to provide electrical energy for the intelligent insulation tester. Specifically, in the present invention, the energy supply component 1 is a hand-crank charger, the rotating end of the hand-crank charger is arranged inside the intelligent insulation tester, and a driving half gear 107 is fixed thereto. The discharge end of the hand-crank charger is connected to the current supply module 106 of the intelligent insulation tester.

[0069] In addition, in the invention, the hand-crank charger also includes: a driving remote handle 102, which is rotatably installed at the center position of the surface of the protective cover 101. The driving remote handle 102 is fixed with a connecting shaft 103 that passes through the protective cover 101 at one end close to the protective cover 101. An electromagnet 104 is fixed to the middle end outside the connecting shaft 103. The electromagnet 104 is placed at the magnetic lines of force between the two permanent magnets 111. In addition, the end of the connecting shaft 103 away from the driving remote handle 102 is fixed to the rotating end, and the rotating end is a column 110.

[0070] It should also be noted that in the present invention, an installation opening is opened at one end of the outside of the intelligent insulation tester, and a commutator sleeve 109 is rotatably installed at the installation opening. The column 110 is adapted to the commutator sleeve 109, and one end of the column 110 is arranged inside the intelligent insulation tester and is fixed to the driving half gear 107.

[0071] It should be added that the installation openings are specifically the first notch 202 and the second notch 304 in the load-bearing component 2 and the sealing component 3 respectively. In addition, in the present invention, the middle section of the commutator sleeve 109 is a disconnected design, and the commutator sleeve 109 is divided into two subset commutator sleeves by means of the disconnected design. The subset commutator sleeves do not contact each other, and a connecting wiring harness is installed between the subset commutator sleeves and the electromagnet 104.

[0072] It should be further added that, in the present invention, brush plates 108 are respectively installed at the top and bottom near the installation port inside the intelligent insulation tester. The brush plates 108 are rotatably connected to the collector rectifier sleeve. Discharge harnesses are respectively installed at one end of the two brush plates 108 facing the interior of the insulation tester. The discharge harness connects the two brush plates 108 to form a discharge end.

[0073] refer to Figures 1-9 It can also be known that in the present invention, a shunt component 4 is installed in the intelligent insulation tester, which is used to store the electrical energy released by the intelligent insulation tester after detecting the insulation performance of the cable connector, and the shunt component 4 operates under the control of the energy supply component 1.

[0074] It should be clear that in the present invention, the shunt component 4 includes: a threaded screw structure, the threaded screw structure is rotatably installed at both ends inside the intelligent insulation tester, one end of the threaded screw structure is fixed with a transmission screw disk 401 that is compatible with the driving half gear 107, the threaded segment 403 in the threaded screw structure is a reverse thread, and the threaded segment 403 is arranged at a position close to the other end of the threaded screw structure, and in addition, a connecting contact module 404 is installed at the movable end of the threaded screw structure, and the connecting contact module 404 and the current receiving module 408 in the intelligent insulation tester are connected when the hand-cranked charger rotates in the opposite direction, and the connecting contact module 404 is slidably installed on the surface of the insulation test circuit board 204 in the intelligent insulation tester, and the outside of the intelligent insulation tester is installed with a capacitor tube 307 that can be replaced with different specifications, and the capacitor tube 307 is used to store electrical energy and is connected to the connecting contact module 404.

[0075] Specifically, in the present invention, sliding notches 206 are respectively provided at the middle ends of both sides of the exterior of the intelligent insulation tester. In the present invention, the threaded screw structure includes: a rod body 407, both ends of which are rotatably mounted on the two ends inside the intelligent insulation tester, specifically on the two ends of the bottom of the sealing cover 301, a transmission screw disc 401 is mounted on one end of the rod body 407, and a threaded segment 403 is arranged at a position near the other end of the rod body 407;

[0076] It should be noted that in the present invention, the movable end is a limit frame 409, the middle part of the limit frame 409 is screwed and installed on the threaded section 403 of the rod body 407, the two ends of the limit frame 409 are respectively adapted to the sliding notch 206, and a force-bearing folding rod 405 is fixed between the bottom end of the middle part of the limit frame 409 and the connecting contact module 404.

[0077] It should be clear that when the threaded screw structure in the present invention is in operation, the limit frame 409 will move along the threaded segment 403 of the rod body 407 as the threaded screw structure rotates, thereby achieving precise control of the connecting contact module 404. The moving range of the limit frame 409 is determined by the length of the sliding notch 206. In the present invention, the length of the sliding notch 206 is the same as the length of the threaded segment 403, ensuring that the connecting contact module 404 is reliably connected to the current receiving module 408 at a specific position.

[0078] In addition, reference Figures 1-9It can also be known that in the present invention, an adjustment notch 306 is opened on one side of the outside of the intelligent insulation tester, and two capacitor slots 411 are installed at the adjustment notch 306. The capacitor tube 307 is clamped and installed between the two capacitor slots 411. The joints of the two capacitor slots 411 pass through the adjustment notch 306 and a stretchable connecting harness is installed between the connecting contact module 404. One of the capacitor slots 411 is fixed to the intelligent insulation tester, and a mounting seat 414 is fixed at a position of the intelligent insulation tester away from the capacitor tube 307. A rebounder 413 is installed on the surface of the mounting seat 414, and one end of the rebounder 413 is fixed to the side of the surface of the other capacitor slot 411 away from the capacitor tube 307.

[0079] It should be clear that in the present invention, the capacitor tube 307 is used to store electrical energy, wherein the capacity of the capacitor tube 307 can be selected and replaced according to actual needs to adapt to the detection requirements of cables of different lengths and specifications. During the discharge process, the capacitor tube 307 is connected to the current receiving module 408 inside the intelligent insulation tester through the connecting contact module 404 to ensure smooth transmission and storage of electrical energy.

[0080] Specifically, in the present invention, the operating mechanism of the shunt component 4 is controlled by the reverse rotation of the hand-cranked charger. When the hand-cranked charger rotates in the reverse direction, the driving half gear 107 drives the transmission screw disk 401 to rotate, thereby rotating the threaded screw structure. Since the threaded segment 403 is a reverse thread, the limit frame 409 will move along the threaded segment 403 of the rod body 407, thereby pushing the connecting contact module 404 to connect with the current receiving module 408. This design ensures precise control and efficient conversion of electrical energy storage.

[0081] In addition, it should be noted that in the present invention, an induction bulb 412 for measuring electricity is installed on the surface of one of the capacitor slots 411. When the electrical energy stored in the capacitor tube 307 increases, the induction bulb 412 will become brighter accordingly, and vice versa. This design allows the operator to intuitively understand the state of electrical energy storage by observing the brightness changes of the induction bulb 412, thereby better controlling the charging speed and time of the hand-crank charger.

[0082] Finally, it should be noted that during actual operation of the present invention, first, the operator charges the intelligent insulation tester through a hand-cranked charger. At this time, the driving half gear 107 drives the transmission screw disk 401 to rotate, thereby rotating the threaded screw structure. Since the threaded segment 403 is a reverse thread, the limit frame 409 will move along the threaded segment 403 of the rod body 407, thereby allowing the connecting contact module 404 to move away from the current receiving module 408.

[0083] During the discharge process of the intelligent insulation tester, the hand-cranked charger is rotated in the direction so that the connecting contact module 404 is connected to the current receiving module 408. At this time, the capacitor tube 307 is connected to the current receiving module 408 inside the intelligent insulation tester through the connecting contact module 404, ensuring the smooth transmission and storage of electric energy. Since the capacity of the capacitor tube 307 can be selected and replaced according to actual needs to adapt to the detection requirements of cables of different lengths and specifications, different capacitor tubes 307 can store different amounts of electric energy.

[0084] In addition, the operating mechanism of the shunt component 4 also includes a feedback link. During the process of storing electrical energy in the capacitor tube 307, the brightness of the induction bulb 412 will change according to the amount of stored electrical energy. The operator can intuitively understand the state of electrical energy storage by observing the brightness changes of the induction bulb 412, thereby better controlling the charging speed and time of the hand-crank charger and ensuring the normal operation of the intelligent insulation tester.

[0085] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
